Wet basements breed mold fast, especially in Guelph's older housing stock. We remediate the mold and point you toward fixing the moisture source for good.
Book a Visit Call 226-790-2661Basement mold follows Guelph's older housing stock. Homes in The Ward, downtown, and Exhibition Park neighbourhoods often have poured concrete or block foundations that allow groundwater seepage. Finished basements trap moisture against walls — by the time mold is visible on drywall, it has typically been growing on the back side for months.
Containment, removal of affected drywall/framing, and antimicrobial treatment for finished or unfinished basements.
Tight-access mold removal in crawlspaces, including vapour barrier and ventilation recommendations.
We identify the seepage or condensation source and recommend waterproofing steps to stop mold from coming back.
Industry-standard remediation (IICRC S520) requires physical containment with negative air pressure and HEPA filtration to prevent spore spread during removal. Affected materials are removed, not just treated — and every job finishes with documentation your insurer or real estate lawyer can rely on.
Pricing depends on the affected area and whether drywall, framing, or flooring needs to come out — see our 2026 cost guide for typical Guelph ranges, or book a visit and we'll assess your specific situation.

Usually groundwater seepage through the foundation, condensation against cold walls, or a finished basement trapping moisture against drywall. We identify the specific source during your visit.
In most cases, yes. We work in tight-access crawlspaces directly, then recommend a vapour barrier or ventilation fix to prevent recurrence.
Sometimes — it depends on the cause. Sudden events like a burst pipe are often covered; gradual seepage or deferred maintenance usually isn't. See our insurance FAQ on the cost guide page.
It depends on the affected area and materials involved. See our cost guide for typical Guelph ranges, or book a visit for an exact quote.
Basement mold is often connected to bigger moisture issues. These pages might help too.
Unsure how far the mold has spread behind drywall or under flooring? We find out before we quote.
Confirm the basement air is clear after remediation with lab-verified sampling.
